this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

objective(s)   although photodynamic therapy is considered as a noninvasive method, most photosensitizers are susceptible to  ultrasound.  therefore,  it  is  expected  that  the  combination of  two  activation  methods  might  have  a synergistic effect. this probable effect has been investigated in this study.   materials and methods   this  study  was  conducted  on  colon  carcinoma  tumor...

Primary squamous cell carcinoma of the colon is extremely rare. The etiology poorly understood, and currently, there are different hypotheses about origin this malignant neoplasm. Here, we r 87-year-old male with a moderately-differentiated nonkeratinizing colon.

A 47 year old female with papillary thyroid carcinoma was referred to our department for post-treatment whole body iodine scanning. The acquired images revealed a focal zone of intense radiotracer uptake in the right lower quadrant of the abdomen. SPECT/CT fused slices showed a focal zone of the radioiodine (131I) uptake in the right colon wall. Colonoscopy revealed a pedunculated po...

Colorectal carcinoma is one of the most common causes of cancer-related death, worldwide. Recently, due to the introduction of novel imaging and therapeutic techniques, five-year survival of patients has increased. However, distant metastasis is still expected in half of the patients. Colorectal cancer tends to target the abdominal cavity, liver, lungs, and bones as the common sites of metastas...

most patients with gastrointestinal cancers refer to the health centers at advanced stages of the disease and conventional treatments are not significantly effective for these patients. therefore, using modern therapeutic approaches with lower toxicity bring higher chance for successful treatment and reduced adverse effects in such patients. the aim of this study is to evaluate the effect of av...

zn (ii) is an important regulator of caspase-3, as well as an antioxidant, microtubule stabilizer, growth cofactor, and anti-inflammatory agent. over the past 30 years, many researchers have demonstrated the important role of zn (ii) in a variety of physiological processes, including growth and development, maintenance and priming of the immune system, and in tissue repair and regeneration. in ...

aim : the aim of this study was to report the anatomical location and histologic type of colorectal polyps in a large series of iranian patients that attended for colonoscopy. background : polyps that develop through the adenoma-carcinoma pathway are considered neoplastic and may eventually progress to invasive carcinomas. in addition polyps can develop with no neoplastic potential. these neopl...

Frizzled-related protein (FRZB) was up-regulated in hepatic metastasis samples compared with primary colon cancer samples in our previous work. However, the clinical relevance of FRZB in colon cancer hepatic metastasis remains uncertain. The aim of this study was to assess the prognostic value of FRZB in patients with colon carcinoma hepatic metastasis after hepatic resection. FRZB expression w...
